I may be way off-base here, but I would expect very few if any apps
are "multi-core aware". Multiple cores get you better performance when
more than one process needs the cpu, but a single I/O-limited process
isn't going to go any faster. Likewise, single-threaded apps can't do
anything with multiple cores even if they aren't I/O limited.
Specialized parallel-programming apps are a different matter, but how
many of those do we typically see on a desktop?
